Objective This study investigated the efficacy, durability and possible adverse effects of passive legraising( PLR) by examining the entire course of cardiovascular responses to PLR. Methods/results Continuous measurements of cardiovascular parameters were performed on eight healthy subjects, using a non-invasive finger blood pressure measurement system during PLR. Blood pressure significantly increased during PLR at each angle of raise:20°, 30°, and 40°.This blood pressure increase was found to be mainly due to an increase in stroke volume, which remained almost constant until the end of the 10 minutes of PLR. No significant differences in values of cardiovascular parameters were found between the different raise angles. Transient changes in cardiovascular parameters occurred when legs were returned to the horizontal position, including considerable transient falls of stroke volume and total peripheral vascular resistance. In patients with deteriorated cardiovascular functions, this might cause a severe transient fall of blood pressure triggering cerebral ischemic attack. Conclusion PLR increased blood pressure mainly due to an increase in stroke volume. The raise angle of 20°was sufficient to produce this PLR effect.

@snowflake_2616 たしかに〜7分って細かく示されてるの気になる。 https://t.co/r3ZI4o5f5D これには、20度の挙上が最も効果で、10分くらいは1回拍出量の上昇があったってかいてる。
@paramedicAI https://t.co/gaQ1RXnWns ありがとうございました 20度でも効果があり10分持続したという報告がありました(^^)
下肢挙上の効果、持続性、リバウンド ✅挙上により血圧上昇、前負荷増大、心収縮性亢進 ✅挙上中の 10 分間はこれら の反応が持続 ✅挙上角度による血圧上昇作用に差はない ✅解除時には血圧低下に注意 https://t.co/aHPps6TVsu
